Joe,
It's been a yr or more since I watched the video and now it's been with a friend for most of that time. I need to get it back from him.
I understand what Jack was trying to say, but once you've taken a set of barrels appart and are putting them back together, you get really concerned about regulating them for not only the convergence but the elevation relative to each other.
When I did that 28g conversion on a 20g LC, the convergence was way off when the muzzles came together, then the POI relative elevation was also somewhat askew even though carefully aligned on the outside of the barrels.
